Hi,
porting gdb to a new target platform i faced the following problem:
Scenario:
Our target processor itself does not support single step & hardware
breakpoints.
But there are two "flavors" of the target system
1. simulation which supports hardware breakpoints & single step (feature
of RTL simulator)
2. concrete hardware using a debugger in ROM via serial link. (no
hardware bp & no single step)
I wrote one target description file (corename-tdep.c) and two remote_*.c
driver for the versions mentioned.
Question:
Currently i can only decide that
- software single step
- hardware breakpoints
are available or not.
(decr_pc_after_break also varies depending on hw-breakpoint
availibility)
How can i make this dependend on the target connection (remote_*.c)
driver selected?
Your answers are greatly appreciated!
Regards,
Michael
